JERSEY CITY — Rep. Albio Sires announced his bid for a fifth term in Congress at Saint Peter’s University yesterday, with a veritable who’s who of Hudson County politics on hand to shower the former West New York mayor with praise.

Sires, 62, a Democrat, said he wants to focus on jobs, immigration reform and making Social Security and Medicare solvent. He said he’d like to work on legislation to create a grant program benefitting local parks and recreation, as well as a bill to improve bike infrastructure and safety.

“It’s not easy when you’re in the minority,” cracked Sires, who represents the 8th Congressional District in the Republican-led House of Representatives.

Almost everyone who holds elected office in Hudson County was on hand for Sires’ announcement, from U.S. Sens. Bob Menendez and Cory Booker to State Sens. Sandra B. Cunningham and Nicholas Sacco to most of the county’s 12 mayors.

Booker, something of a national celebrity, caused a stir when he arrived 45 minutes late. State Sen. Raymond Lesniak, seated on the dais, bowed and yelled, “We’re not worthy, we’re not worthy.”

Booker, Lesniak and the other elected officials who spoke painted Sires as an experienced legislator who remains committed to his constituents.

“This man knows how to pull the right levers of government,” said Lesniak, D-Union.

Sires was first elected to Congress in 2006, succeeding Menendez when Menendez moved on to the Senate. The 8th Congressional District covers most of Hudson County and stretches into parts of Essex and Union counties.

With the entire Democratic establishment behind him, Sires is considered a shoo-in to win the June 3 primary and the Nov. 4 general election.
